hi,

i have read the icsp guide in the microchip website (https://ww1.microchip.com/downloads/en/DeviceDoc/30277d.pdf)

i focused on the 16f8x programming. there is a circuit at the bottom of page 2-21 (figure 1: typical application circuit). i am very noob in icsp/isp and i would like to learn using it... i have several questions that really need clarification:

- is the diode found in mclr/vpp already enough?
- can a simple tri state buffer be used as an isolation for rb7 and rb6? i found this (https://focus.ti.com/lit/ds/symlink/sn74lvc2g240.pdf)
- if i use tri-states, is there a way to automatically switch the gates to its its hi-z state during programming? or i simply need to place jumpers/dip switches to make it hi-z?

if there is further information that may be useful, plese feel free to add...

thanks! :)
